Postcode to UK Health Authorities (HSCB, HB/CHP, LHB, NHS)

This instant download contains every UK Postcode (circa. 1,791,296 Postcodes) and the Postcode’s  associated Health Authority.  In addition, we include a list of circa. 892,441 ‘Retired’ Postcodes that are no longer used by Royal Mail, showing historic HA data.  The product files are updated quarterly to ensure they remain current, and our clients receive an inclusive complete refresh every three months as part of the service, for no additional fee.


The product format is Comma Separated Variable (CSV). The CSV output consists of three text files with header records and will open in any common application including SQL, Word, MS Access and MS Excel.   Initially you receive one ZIP compressed file, that when unpacked will reveal three files: (1) HEA-FLL-UK-CSV-1 containing all live Postcodes from Postcode Areas AB to LN (837,145 postcodes); (2) HEA-FLL-UK-CSV-2 containing all live Postcodes from Postcode Areas LS to ZE (828,610 postcodes); (3) HEA-FLL-UK-CSV-Retired containing all circa. 812,515 Retired Postcodes & historic HA data.

Fields presented in the files:

  • Full Postcode (e.g. UB7 0EB)
  • Postcode Sector (e.g. UB7 0)
  • Postcode District (e.g. UB7)
  • Postcode Area (e.g. UB)
  • Area Code*
  • Area Name* (e.g. NHS North West London CCG)
  • Region Code* (e.g. E18000007)
  • Region Name* (e.g. London)
  • Country (e.g. England)

  • Postcode Retired* – date Postcode was retired

*Area Code: The code for the CCG areas (England), LHBs (Wales), CHPs (Scotland) – now defunct, LCG (Northern Ireland) and PHD (Isle of Man; there are no equivalent areas in the Channel Islands (for which a pseudo code is included). The field will otherwise be blank for postcodes with no grid reference.  *Area Name: The names for the above Area Codes.  *Region Code: The Health Area Code for the postcode: Former Strategic Health Authority (SHA)/ Local Health Board (LHB)/ Health Board (HB)/ Health Authority (HA)/ Health & Social Care Board (HSCB). SHAs were abolished in England in 2013 but the codes remain as a ‘frozen’ geography.  *Region Name: The names for the above regions.  *Retired Postcodes: Contains Postcodes which have now been retired from the Postal system and therefore are no longer in circulation. This file provides a comprehensive ‘history’ of Postcodes and the current Health Authority structure. It is recommended to use this data file in conjunction with the ‘live’ files (1) HEA-FLL-UK-CSV-1 containing all live Postcodes from Postcode Areas AB to LN (837,145 postcodes); (2) HEA-FLL-UK-CSV-2 containing all live Postcodes from Postcode Areas LS to ZE (828,610 postcodes) to achieve the maximum match rates for accurate analysis.


The organisation of the NHS differs between each of the UK’s four countries of England, Scotland, N. Ireland and Wales.

English Health Geography

On 1 April 2015 the 25 NHS area teams (NHSAT) merged and were renamed to form 13 regions (geography) (NHSRG). On 1 April 2016 the number of NHSRGs increased to 14 and in May 2017 they were renamed to NHS England (Region, Local Offices) (NHSRLO). At the same time, the four NHS commissioning regions (NHSCR) were renamed to NHS England (Regions) (NHSER).

Welsh Health Geography

The structure after 1 October 2009 – The current structure of health administration in Wales came into effect on 1 October 2009. A total of 22 local health boards (LHB) merged to form seven, with each LHB covering one or more Welsh unitary authority (UA). These LHBs report to the three regional offices within the NHS Wales Department of the National Assembly.

Scottish Health Geography

Scotland has 14 health boards (HB), which form the upper tier of the Scottish health care system and report directly to the Scottish Government. The 34 community health partnerships (CHP) formed the lower tier of the Scottish health administration until they were abolished on 31 March 2015.

Northern Ireland Health Geography

The structure after 1 April 2009.  The current structure of health administration in Northern Ireland came into effect on 1 April 2009. A single health and social care board (HSCB) replaced the four former health and social services boards (HSSB). The board focuses on commissioning, resource management, performance management and improvement. It identifies and meets the needs of the local population through its five local commissioning groups (LCG). LCGs are sub-committees of the HSCB.
